I have been using Matrix since I’ve been on Lemmy. It’s an open source encrypted chat application, and obviously Lemmy DMs are not encrypted so it’s kinda necessary for private communication. I have a few questions though.

Is there a community about Matrix on Lemmy?

Is Matrix technically part of the fediverse? I noticed it does not appear on fedidb.com. On a related note, what is the active userbase size?

Who is the developer/team and do they have an active presence on the fediverse?

Thank you for anyone who can answer my questions and also to the Matrix devs, I greatly appreciate you. But I am just curious about some of the details about Matrix which I already know about for Lemmy, Piefed, Mbin, etc. Matrix is an essential component of the fediverse ecosystem, so I think it would be prudent to have a greater understanding of it and potentially seek more cross-pollination and/or collaboration between the threadiverse and Matrix.
